This document continues the Phase 1 work reported in AD-A030 762. That contract was concerned with (1) evaluation of a few specific structures, and (2) devising expedient options for upgrading their structural resistance to blast. The new work was not restricted to expedient options using only indigenous materials and labor, but could also include predesigned options, stored materials, and pre-arrangements for construction trade specialists. The work was to: cover specific 'how-to-do-it' applications to be crisis-implemented in a 2- to 3-day period; include quick, inexpensive closure options; and, provide for critical workers remaining behind in risk areas, plus check of the options, potential for CRP implementation ('host areas'). All applications are to basements, as defined in the first-phase report. This report includes appendices on: predesigns and fabrication of plywood stressed-skin panels (PSSPs); a design procedure for PSSPs used as intermediate (beam-column) supports for beams/girders in the floor over a potential basement shelter; using plywood panels by developing a design procedure for their use alone as closures in potential basement shelters; simplified charts for use on aperture closures of 2-by materials for use by a semi-skilled artisan (carpentry); and typical availability of wood and plywood in local lum-beryards, plus detailed data on species, sizes, stress grading and some grades.
